commit 00abf69dd24f4444d185982379c5cc3bb7b6d1fc upstream. xfstest generic/452 was triggering a "Busy inodes after umount" warning. ceph was allowing the mount to go read-only without first flushing out dirty inodes in the cache. Ensure we sync out the filesystem before allowing a remount to proceed.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
